This article examines the history of Japanese encephalitis (JE) research and disease control in South Korea from the post-liberation era through the 1990s, focusing on the gap between the accumulation of scientific knowledge and its translation into effective public health policy. Drawing on epidemiological reports, government documents, medical journals, and newspaper sources, this study analyzes three interconnected dimensions of Korea’s JE history. First, it traces how knowledge about JE was produced through transnational networks—including U.S. military medical laboratories, the World Health Organization’s malaria eradication program, and Korean scientists trained abroad. As such, this body of knowledge was externally structured, rather than through an independent domestic research infrastructure, and thus it failed to translate consistently into government prevention policy. Second, this study examines how DDT-centered vector control became the principal instrument of JE prevention, and how the repeated limitations of insecticide-based interventions helped produce a discourse that attributed outbreaks to rural backwardness. This narrative deflected attention from the structural deficiencies of the prevention system itself. Finally, this study shows that vaccination—long anticipated as the solution to JE—also faced its own institutional obstacles. The failure to secure adequate funding, the privatization of vaccine production, the shift to fee-based individual vaccination, and the absence of mandatory vaccination requirements collectively delayed stable preventive coverage until the mid-1980s, when rising vaccination rates finally produced a sustained decline in JE incidence. Taken together, this history demonstrates that the management of JE in modern Korea was shaped less by the availability of scientific knowledge or biomedical technology than by the presence or absence of the institutional foundations necessary to operationalize it.

Objectives: This study aimed to develop a NOVA-based scoring approach for evaluating ultra- processed food (UPF) intake among Korean adults and to examine its performance. Previous studies have reported that young adults have the highest levels of UPF consumption. Accordingly, this study focused on adults aged 19–40 years and developed scoring components reflecting dietary patterns specific to Korean eating habits. Methods: Using 24-hour dietary recall data from adults aged 19–40 years in the Korea National Health and Nutrition Examination Survey (2021–2023), foods were classified according to the Korean-adapted NOVA system. The top 10 food groups accounting for ≥ 80% of cumulative UPF-derived energy were selected to construct the scoring components. The tool was operationalized using food frequency questionnaire (FFQ) data from the Gangwon cohort study (2022–2024). Intake frequencies were converted into scores ranging from 0 (“rarely or never”) to 5 (“≥ 1 time/day”), and summed to generate the NOVA–UPF score (range: 0–50). Results: Among 237 young adults (aged 20–49 years), the mean NOVA–UPF score was 22.9 ± 8.3. A positive association was observed between the NOVA–UPF score and FFQbased UPF energy intake (Spearman’s ρ = 0.629, P < 0.001). Cross-classification showed that 51.9% were classified into the same tertile and 94.9% into the same or adjacent tertiles, with a weighted kappa coefficient of 0.279. Conclusion This NOVA-based scoring approach may serve as a preliminary tool for assessing UPF intake in Korean young adults. Further refinement and rigorous validation using quantitative dietary assessment methods and more diverse populations are required before broader application.

This article examines the historical trajectory of South Korea’s maternal and child health (MCH) programs from the late 1970s to the 1980s, focusing on the establishment and operation of MCH centers funded by the World Bank population loan. It investigates how these centers reflected the evolving relationship between population control policies and public health services within South Korea's developing healthcare system.
The MCH centers, established nationwide but primarily located in rural areas, were intended to improve maternal and infant health indicators while ultimately contributing to fertility reduction. Despite the ambitious vision of integrating family planning with comprehensive maternal and child healthcare, the centers faced significant challenges, including funding shortages, difficulties in recruiting midwives, and competition from the rapidly expanding private medical sector, which offered modern diagnostic technologies and access to specialist physicians. In response, the government attempted to redirect remaining funds toward establishing comprehensive MCH centers within private hospitals; however, this shift did not substantially increase the utilization of local MCH centers.
This study demonstrates that, despite the rhetoric emphasizing maternal and child health, MCH programs remained subordinate to fertility control objectives within South Korea’s population policy framework. The history of these centers highlight the tension between demographic goals and public health service needs, as well as the complex interplay between international development organizations, national policy priorities, and local healthcare practices during a period of rapid social transformation in South Korea.

Objectives: This study investigated the awareness and acceptance of digital therapeutics (DTx) among psychiatrists in South Korea, providing empirical insights to support future clinical implementation and dissemination. Methods: An online survey targeting 50 psychiatrists was conducted from October 2024 to February 2025. Descriptive statistics were performed on completed responses (n=36), focusing on DTx-related awareness and acceptance. Results: Most participants were aware of DTx, but few had experience prescribing it. They had positive expectations of increased treatment options and efficacy, with most information obtained through exhibitions and conferences. The key factors influencing the intention to use included reimbursement availability and the feasibility of integration with the electronic medical records. Many were motivated by interest in novel treatments and were willing to use DTx if peer adoption increased. The primary concern was uncertainty around reimbursement, and DTx was generally preferred as an adjunctive treatment. The appropriate cost for six sessions was considered to be 150000 KRW (approximately 110 USD) or less. The participants emphasized evidence-based effectiveness, convenience, and efficiency when promoting patient engagement. The need for incorporating DTx education into psychiatric residency training was also recognized. Conclusion This study is the first of its kind in South Korea to explore psychiatrists’ perspectives on DTx, offering foundational insights to help develop policy and education strategies for clinical and institutional implementation.

Objectives: A campus-based intervention to enhance food literacy (FL) and establish exercise habits among college students was developed and the program’s effectiveness was evaluated. Methods: The 13-session program was developed based on the transtheoretical model and social cognitive theory. Junior and senior students majoring in food and nutrition and physical education were asked to participate as mentors, with freshmen and sophomores from varied majors as mentees. The program encompassed food, nutrition, and exercise lessons including cooking sessions. Data were collected via pre- and post-program surveys using a questionnaire consisting of items on FL and nutrition behaviors and physical fitness measurements. Results: Among 39 participants (35.9% male, 64.1% female), the overall FL score increased significantly from 64.1 to 70.6 post-program (P = 0.001). Significant increases were observed in the nutrition and safety (P < 0.001), cultural and relational (P = 0.023), and socio-ecological (P = 0.001) domains, as well as knowledge (P = 0.001), self-efficacy (P = 0.013), attitude (P < 0.001), and behavior (P = 0.005) items in three domains of FL. Additionally, meal duration increased significantly (P = 0.007) and sit-up performance among female showed a meaningful change (P = 0.046). Changes in dietary behaviors significantly progressed (P = 0.015) while that in exercise habits approached a marginal significance (P = 0.053) after the intervention. Conclusion The results reveal positive changes in FL and some modifications in eating habits, although the program had limited effects on physical activity and fitness measurements. These findings suggest that strategic approaches to foster exercise behavior changes in college students are required. This pilot program can serve as foundational data for improving and expanding multicomponent health promotion programs for this population.

This paper aims to historically re-evaluate the issues surrounding resident participation in health care and its legacy by examining the community participation in health care. In the 1970s and 1980s, community participation was one of crucial trends and a controversial topic in the international health as well as the international aid. Throughout the 1970s, local participation was regarded as one of essential elements for the access to basic healthcare and primary health care in developing countries. Community health projects which aimed to apply primary health care were implemented in rural areas and some urban areas in the 1970s and 1980s. Village Health Workers(VHWs) were a symbolic example of community participation in these projects. They consisted of local women and led health activities with simple skills in their villages. They served as a bridge between the project team and the residents. Health professionals expected them to be health leaders for “self-help” in health of their communities. In the mid-1980s, however, as the number of health facilities and professional health care workers increased, the activities of VHSs were decreased. The mixed understanding of the responsibilities and roles of VHSs among the health professionals affected the skeptical view on the achievement and effects of community participation in health care. In the mid-1980s, as the government officially organized the VHWs, the dilemma surrounding community participation intensified. When the community health projects were ended, most of the VHW organizations were also disbanded. After the projects, the spirit of community participation was only inherited by some healthcare movement organizations, such as medical cooperatives.

BACKGROUND/OBJECTIVES: The aim of this study was to examine the validity and reproducibility of a food frequency questionnaire (FFQ) developed in Korea for breast cancer survivors. SUBJECTS/METHODS: Ninety-nine breast cancer survivors who completed an FFQ twice and three 3-day dietary records (DRs) between 2016–2017 were included. Energy and 14 nutrient intakes were calculated from FFQs and DRs. To determine the validity of the FFQ, energyadjusted de-attenuated Pearson correlations between two FFQ assessments and the average of the three 3-day DRs were calculated, and to determine reproducibility, energy-adjusted Pearson correlations and degrees of agreement were calculated between the first and second FFQ assessments. RESULTS: Correlation coefficients of validity ranged from 0.29 (protein) to 0.47 (fat) (median value = 0.36) for the FFQ assessment and from 0.20 (riboflavin) to 0.53 (calcium) (median value = 0.37) for the second. Correlation coefficients of reproducibility ranged from 0.22 (sodium) to 0.62 (carbohydrate) (median value = 0.36). Regarding FFQ reproducibilities, percentage classifications of exact agreements for energy-adjusted nutrients ranged from 27.3% (sodium) and 45.5% (fat). A median 76.8% of participants were classified into the same or adjacent quartiles, while a median of 5.6% of participants were classified in extreme quartiles. Bland–Atman plots for the majority of data points of three macronutrients, calcium and vitamins A and C fell within limits of agreement. CONCLUSIONS These results indicated that the newly developed FFQ for Korean breast cancer survivors has acceptable validity and reproducibility as compared with three 3-day DRs collected over a one-year period.
